Camera bug
This post isn't about how you ruined Fiora this time Riot...
You have a camera bug.
If you Alt Tab out of the game and come back the camera will sometimes be stuck open.
There is no way to correct the open camera problem with the icons or hot key.
The only way to fix the issue is to Ctrl Alt Delete and close the program from windows and restart the game.
Just a FYI
Because I care! Unlike you Fiora haters...
